Description

Technical Field

[0001] This utility model relates to the technical field of rubber tire production equipment, specifically a rubber tire film winding device. Background Technology

[0002] At the end of the rubber tire production chain, the packaging process is crucial. Traditionally, the film wrapping of tires has relied heavily on manual labor. Workers had to manually wrap the film roll around the tire, which was not only extremely labor-intensive but also highly inefficient.

[0003] During manual packaging, human strength is limited, and repetitive labor over a long period can easily lead to hand fatigue, resulting in decreased stability of the wrapping action and inconsistent film tightness. Areas that are too loose cannot provide sufficient protection for the tires, making them susceptible to damage from collisions and friction during subsequent transportation and handling. Areas that are too tight may cause indentations on the tire surface, affecting the tire's appearance and potentially damaging its internal structure, thus reducing product performance.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Please see Figures 1-4 The image shows a rubber tire film winding device, which includes a base 1 on which a tire carcass driving device 2, a film winding device 3, an adjustable tire carcass clamping device 4, and a tire carcass auxiliary feeding device 5 are disposed.

[0017] The tire drive device 2 is mounted on the base 1 to provide rotational power to the tire, enabling the tire to rotate at a set speed and direction for film winding operations.

[0018] The tire carcass drive unit 2 includes a drive motor 201 and two symmetrically arranged rollers 202. The drive motor 201 is mounted on the lower end face of the base 1. This mounting method utilizes the stability of the base 1 to reduce vibration generated during motor operation. Both rollers 202 are mounted on the base 1 via seated bearings. The seated bearings provide stable support for the rollers 202, ensuring that the rollers 202 can rotate flexibly.

[0019] One of the two rollers 202 is connected to the drive motor 201 at one end via a synchronous belt 302d and a synchronous pulley. The two rollers 202 are also connected to each other via a synchronous belt 302d and a synchronous pulley. When the drive motor 201 starts, its output shaft drives the connected synchronous pulley to rotate, transmitting power to the first roller 202 through the synchronous belt, causing it to rotate. Since the two rollers 202 are also connected via a synchronous belt 302d and a synchronous pulley, the rotation of the first roller 202 will drive the other roller 202 to rotate synchronously. When the film is placed on the two rollers 202, the friction between the rollers 202 and the film causes the film to rotate, thus providing the necessary conditions for film winding.

[0020] The film winding device 3 is mounted on the base 1 and located on one side of the tire carcass drive device 2. Its main function is to accurately and evenly wind the film onto the rotating tire carcass.

[0021] The film winding device 3 consists of a vertical mounting plate 301, a drive assembly 302, a rotating assembly 303, and a film mounting assembly 304. The vertical mounting plate 301 serves as the supporting structure for the entire film winding device 3, providing a foundation for the installation and fixation of other components.

[0022] Driver component 302.

[0023] The drive assembly 302 includes a rotary motor 302a, a main pulley 302b, two auxiliary pulleys 302c, and a timing belt 302d. The main pulley 302b is located in the upper part between the two auxiliary pulleys 302c. This layout enables the timing belt 302d to maintain stable tension during transmission, thereby improving transmission efficiency.

[0024] The main pulley 302b and two auxiliary pulleys 302c are connected together by a synchronous belt 302d. The main shaft of the rotary motor 302a is directly connected to the main pulley 302b. When the rotary motor 302a starts, its main shaft drives the main pulley 302b to rotate. The main pulley 302b transmits power to the two auxiliary pulleys 302c through the synchronous belt 302d, causing them to rotate synchronously.

[0025] The rotating assembly 303 consists of multiple auxiliary rollers 303a and an open ring 303b. The auxiliary rollers 303a are provided with annular limiting grooves 303c, and the side of the open ring 303b matches the limiting grooves 303c.

[0026] Multiple auxiliary rollers 303a are evenly mounted on the vertical mounting plate 301, surrounding the open ring 303b. Each auxiliary roller 303a is connected to the vertical mounting plate 301 via a belt-shaft connecting shaft, thus the multiple auxiliary rollers 303a collectively clamp the open ring 303b in the middle. The side of the timing belt 302d closest to the open ring 303b abuts against the open ring 303b.

[0027] When the timing belt 302d rotates under the drive of the drive assembly 302, the abutting action between the timing belt 302d and the open ring 303b causes the open ring 303b to perform circular motion under the limiting action of the auxiliary roller 303a. The limiting groove 303c of the auxiliary roller 303a can prevent the open ring 303b from shifting during rotation, ensuring its rotational stability.

[0028] The film mounting assembly 304 includes a film roll support crossbar 304a fixedly connected to an open annulus 303b. The support crossbar 304a has two symmetrically arranged conical abutment blocks 304b, which can slide on the support crossbar 304a. A quick-release clamp 304c is provided at the end of the support crossbar 304a away from the vertical mounting plate 301.

[0029] During film installation, the film roll is placed on the support crossbar 304a, and then the sliding conical abutment block 304b is used to position the film roll from both sides, ensuring accurate positioning of the film roll on the support crossbar 304a. Finally, the quick-release chuck 304c is used to secure the film roll and prevent it from loosening during winding. As the open ring 303b rotates, the film roll also rotates, thus evenly winding the film onto the rotating tire carcass.

[0030] The adjustable tire clamping device 4 is located on one side of the film winding device 3. Its main function is to maintain the vertical state of the tire during the rotation of the tire, so as to ensure the uniformity and stability of the film winding.

[0031] The adjustable tire clamping device 4 includes two horizontal sliding rods 401 arranged symmetrically at the top and bottom, two vertically arranged vertical connecting plates 402, a side clamping roller shaft 403, and an adjusting cylinder 404.

[0032] The two ends of the two horizontal slide bars 401 are connected to the vertical mounting plate 301 by bolt-type shaft clamps. This connection method ensures the installation stability of the horizontal slide bars 401 and facilitates disassembly and adjustment. Each horizontal slide bar 401 is connected to two vertical connecting plates 402 via sliding sleeves, allowing the vertical connecting plates 402 to slide freely on the horizontal slide bars 401. Two adjusting cylinders 404 are provided, symmetrically fixed on the two vertical mounting plates 301, and the extension rod of each adjusting cylinder 404 is connected to the adjacent vertical connecting plate 402. Each vertical connecting plate 402 has a clamping roller shaft 403 symmetrically provided at both its upper and lower ends.

[0033] When clamping tires of different sizes is required, the extension and retraction of the adjusting cylinder 404 is controlled. The extension rod of the adjusting cylinder 404 causes the vertical connecting plate 402 to slide on the horizontal slide rod 401. The sliding of the vertical connecting plate 402 causes the clamping roller 403 to move closer to or further away from the tire, thereby achieving the clamping or releasing operation of the tire. In this way, it is possible to flexibly adjust according to the actual size of the tire, ensuring that the tire remains in a stable vertical position during rotation.

[0034] The tire body auxiliary feeding device 5 is installed on the base 1. Its main function is to assist in completing the tire body feeding operation, improve feeding efficiency, and reduce manual labor intensity.

[0035] The tire carcass auxiliary unloading device 5 includes a linear guide rail pair 501, a lifting cylinder 502, a removal cylinder 503, and a lifting plate 504. The lifting plate 504 is located on the lower side of the tire carcass, and the lifting plate 504 is provided with an arc-shaped support groove 505. The shape of the arc-shaped support groove 505 is adapted to the bottom of the tire carcass, which can better support the tire carcass.

[0036] Linear guide rail pair 501 is fixedly mounted on base 1. The cylinder body of lifting cylinder 502 is fixedly connected to the slider of linear guide rail pair 501, and its telescopic rod is connected to the lower end face of lifting plate 504. The cylinder body of removal cylinder 503 is connected to base 1, and its telescopic rod is connected to the slider of linear guide rail pair 501.

[0037] When the film is wound and the unloading operation is required, firstly, the lifting cylinder 502 is activated, extending its telescopic rod. The telescopic rod of the lifting cylinder 502 pushes the lifting plate 504 upward, and the arc-shaped support groove 505 on the lifting plate 504 contacts the bottom of the tire carcass, lifting it and detaching it from the roller 202 of the tire carcass drive device 2. Then, the removal cylinder 503 is activated, and the telescopic rod of the removal cylinder 503 moves, causing the slider of the linear guide pair 501 to slide on the guide rail, thereby moving the lifting plate 504 and the tire carcass on it along the linear guide pair 501, removing the tire carcass from the device, and completing the unloading operation.

[0038] Working principle: The operator moves the rubber tire carcass to be wrapped with film to the rubber tire film winding device and places it stably on the two symmetrically arranged rollers 202 of the tire carcass drive device 2. At this time, the tire carcass is in the working position of the device, ready for the subsequent film winding operation. Simultaneously, the film roll is installed onto the film mounting assembly 304 of the film winding device 3. Specifically, the film roll is placed on the film roll support crossbar 304a, which is fixedly connected to the open ring 303b. Next, the two symmetrical conical abutment blocks 304b, which are slidably arranged on the support crossbar 304a, are pressed against the inner hole of the film roll to initially fix the film roll. Finally, the quick clamp 304c at the end of the support crossbar 304a away from the vertical mounting plate 301 is used to further clamp the film roll, ensuring that it will not loosen during the winding process. Based on the size of the tire carcass, the operator activates the adjusting cylinder 404 of the adjustable tire carcass clamping device 4. The telescopic rod of the adjusting cylinder 404 pushes or pulls the vertical connecting plate 402 connected to it. Since the vertical connecting plate 402 is connected to the horizontal sliding rod 401 through a sliding sleeve, and the two ends of the horizontal sliding rod 401 are connected to the vertical mounting plate 301 through bolt-type shaft clamps, the vertical connecting plate 402 will slide along the horizontal sliding rod 401. The side clamping rollers 403, which are symmetrically arranged at the upper and lower ends of the vertical connecting plate 402, gradually approach the tire carcass as the vertical connecting plate 402 slides, until they are in close contact with the side of the tire carcass, ensuring that the tire carcass remains vertically stable during rotation and preventing it from shifting or shaking.

[0039] The operator starts the drive motor 201, which generates power. This power is transmitted to one of the rollers 202 via a synchronous belt and pulley, causing that roller to rotate. Since both rollers 202 are also connected by a synchronous belt and pulley, the other roller 202 will also rotate synchronously. The synchronous rotation of the two rollers 202 causes the tire carcass placed on it to rotate at a uniform speed, providing a stable rotational foundation for film winding.

[0040] The operator starts the rotary motor 302a, and the main shaft of the rotary motor 302a drives the main pulley 302b to rotate. The main pulley 302b and the two auxiliary pulleys 302c are connected together by the synchronous belt 302d. The rotation of the main pulley 302b is transmitted to the two auxiliary pulleys 302c through the synchronous belt 302d, so that they rotate synchronously.

[0041] The synchronous belt 302d abuts against the open ring 303b on the side closest to it. Driven by the synchronous belt 302d, the open ring 303b begins to rotate around multiple auxiliary rollers 303a. The annular limiting groove 303c on the auxiliary rollers 303a matches the side of the open ring 303b. The multiple auxiliary rollers 303a are evenly arranged around the open ring 303b and connected to the vertical mounting plate 301 via a belt-shaft connecting shaft, which together ensures the stability of the rotation of the open ring 303b.

[0042] As the open annulus 303b rotates, the film roll mounted on the film mounting assembly 304 also rotates. Under the combined action of the tire carcass rotation and the film roll rotation, the film gradually unfolds from the film roll and evenly wraps around the rotating tire carcass surface. Throughout the winding process, the carcass drive device 2 continuously provides stable rotational power to the carcass, and the adjustable carcass clamping device 4 ensures the stable upright position of the carcass, ensuring that the film can be tightly and smoothly wrapped around the carcass.

[0043] After the film wrapping operation of the tire carcass is completed, the operator activates the lifting cylinder 502 of the tire carcass auxiliary unloading device 5. The telescopic rod of the lifting cylinder 502 extends upward, pushing the lifting plate 504 to rise. The arc-shaped support groove 505 on the lifting plate 504 is adapted to the bottom shape of the tire carcass, which can stably support the tire carcass and lift it a certain height from the roller 202.

[0044] After the tire body is lifted, the operator activates the removal cylinder 503. The telescopic rod of the removal cylinder 503 pushes or pulls the slider of the linear guide pair 501, causing the slider to move along the linear guide pair 501. Since the cylinder body of the lifting cylinder 502 is fixedly connected to the slider of the linear guide pair 501, the lifting plate 504 and the tire body on it will also move along the linear guide pair 501, thereby removing the tire body from the working area and completing the automatic unloading operation.

[0045] After the material is unloaded, the operator controls the lifting cylinder 502 and the removal cylinder 503 to reset, so that the lifting plate 504 returns to its initial position, preparing for the loading of the next tire carcass and the film wrapping operation. At the same time, the adjusting cylinder 404 of the adjustable tire carcass clamping device 4 can also adjust the side clamping roller 403 to a suitable initial position as needed to accommodate the next tire carcass of different sizes.
